We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).

joelsherrill writes "RTEMS is a free real-time operating system for embedded systems. The project is celebrating the 21st birthday of RTEMS today. RTEMS supports the single process with filesystem POSIX profile on over a dozen processor architectures. To just be entering young adulthood, RTEMS has had a busy life. It has been a Google Summer of Code project twice (Thanks Google!). It has been to Venus on the Venus Express, circles Mars on the Electra radio, powers Herschel and Planck, is on its way to the asteroid belt aboard DAWN, and has been a key part of physics discoveries at the Stanford Linear Accelerator Center."

You laugh, but there's no other signifigance to "21 years". This would have been better celebrated LAST year.

Why? It's an important time in a young operating system's life -- Throw some 0xDEADBEEF on the registers and bring the free beer, it's party time! Derive safely, RTEMS, and don't BSOD or have unsafe hex while you're out.

RTEMS is a very nice, robust, reliable deeply embedded RTOS with modern design philosophies and well defined maximum operational latencies. I worked with a specialty hardware design firm sometime around 1997 to get RTEMS ported to a new embedded board (PMC module with PPC processor, dual 100BaseT, and a boatload of DRAM) I had commissioned from them. RTEMS worked out so well for them that they sold quite a few other embedded board products with RTEMS after this, until being purchased by a larger company t

You're not alone. I've been involved in computing technology since the 1970's, write a column on embedded engineering and recently wrote a series of four articles on embedded RTOSs, but also have never heard of it. Until now. Duh!

For those who are interested, FreeRTOS is a very interesting embedded RTOS.

RTEMS targets a different POSIX profile than GNU/Linux. RTEMS provides a single process, multi-threaded environment with either constant or predictable execution times for nearly every service. A small RTEMS system would be 64Kb total code and data space but that would not be the smallest possible. A large RTEMS system with BSP TCP/IP, filesystem, webserver, and telnetd will fit into less than 512Kb code space. This is tiny, if not impossible, for a GNU/Linux system.

Well, I've been to Venus on the Venus express too, I've circled Mars (but never landed), I've powered her bell and spank, been on my way to a steroid belt aboard Dawn, and I've been a key part of clinic discoveries too. Where's my f**king parade?//Says the gay girl.

previous homoerotic behaviors become depressingly heteronormative at that point.

It's all about market share. I've been with a number of bi-curious women who are comfortable doing damn near anything with another female, "So long," as one of them put it, "there's a penis in the room." As supplier of said organ I've never had a problem with that, but I can see it could be kinda depressing from a certain perspective. "Lesbian porn" that can appeal to that audience of hetero-experimentalists will make a lot m

That's why lesbians are so wary of "bi-curious"... they're heart breakers. so you want to experiment, fine... just own up to that ahead of time. Most don't, and that's why they have such a poor reputation amongst women. bi-curious guys, otoh -- in a word, Jack Harkness. *sighs*

Well, keep in mind that most of it is obviously written ABOUT and not FOR you. It's FOR men who apparently like to fantasize that all you gals just want one of us there. Which is obviously ridiculous, but most porn is based on equally unlikely fantasies, and it sells anyway.

But the Top Gear angle intrigues me. I'm already looking at an offtopic mod, so what the hell, can you elaborate on that? It's OK if you'd rather not.

Apparently yes. I should have figured it. Some things are apparently constant among all Americans, and finding the British accent desirable seems oddly to be one of them. And the Brits do have a flair for designing gorgeous cars.

If you want to see a lesbian cream herself over a car, two words: Shelby Cobra. Specifically, the 1967 Ford Mustang Shelby Cobra 500 (it's the one with the police interceptor block), with the "Le Mans" stripes and trim, preferably blue. I prefer the hard top, but a lot of girls prefer the converible. They are sad. And it needs to be the MT, not the AT -- because have an AT in that car should be a shooting offense.

Sexist?? WTF. That does not have anything to do with “sexism”.By far most men are hetero. By far most women too. (Hetero) men watch by far more porn than women.So obviously, nearly all porn is for hetero men. Some for hetero women or couples. Some for gay men. And very little for gay women.Everything else would be a weirdly distorted market.

Buy enough porn that you like, and you get more. But don’t act as if you were entitled to anything. Especially if you most likely don’t pay anyth

The market of lesbian porn for lesbians is, I imagine, pretty small in comparison to the market for lesbian porn for heterosexual males. The whole porn industry is geared towards what will sell to the maximum number of people for the lowest investment of time, effort, and/or bodily fluids.

Jake.. 2009 was one of the most active years yet. The Google Summer of Code students were absolutely wonderful. I have pushed on test coverage to get as close as possible to 100%. Santosh was the GSoC student who worked with me and we got test reports near 100% on 5 target architectures (x86, sparc, powerpc, arm, and m68k/coldfire).
